7.1 CP-1037 Cable Assembly

An optional cable assembly, Omega product number CP-1037, is available to convert the IOP-241's 33-pin 0.8mm I/O connector to a standard D-37 male connector. The first 31 connections on the IOP-241 map directly to the first 31 pins of the D37 connector. Note that two of the IOP-241 ground connections (pins 32 and 33) are not available when using the CP-1037. Figure 7-1 illustrates the D37 connector pin assignments.
